Title: Direct driving motor system
Inventor: ONO YUTAKA
IPC: H02P6/17
Filed: 1987-03-02
Abstract: PURPOSE:To optimally control a DC motor by using a specific optical rotary encoder, providing a position controller and a speed controller, and regulating its servo system by a tuning unit. CONSTITUTION:A DC motor system has a motor section 100, its driving circuit 200, an encoder section 300 having an encoder 3001 and its interface 3002, a speed controller 400, a position controller 500 and a tuning section 600 for regulating servo systems of both the controllers. The section 300 has two stages of slits for detecting the position by the optical rotary encoder, and the difference of the number of the slits is set to the same number as that of the teeth of the motor. As a result, the displacement of the phases of the stator teeth of the motor from the rotor teeth can be obtained directly from the phase difference of the waveform signal of the slit passing lights. Thus, it can be detected by high resolution.

IPC: B23K26/21
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a welding method wherein the finishing is kept good and workability is significantly improved. SOLUTION: A body 4 and a side plate 5 are mutually abutted. The abutted portion is fastened by screws at a given pitch. The screw fastening pitch is loose at a start end of welding processing, and becomes dense as approaching a finish end. Thereby, thermal distortion due to the temperature risen according to the proceeding of the welding processing is prevented by the dense-pitched screw fastening, and the increase of screw fastening portions is restrained to minimum.

Title: Electron beam exposure method
Inventor: MIYAZAKI TAKAYUKI
IPC: H01L21/30
Filed: 1985-03-11
Abstract: PURPOSE:To prevent the generation of an error in detection of positioning mark by a method wherein the range of selection of signal-noise ratio of the signal with which the positioning mark on a wafer is detected by an electron beam is set based on the signal obtained by scanning an electron beam on the pattern located on the wafer. CONSTITUTION:The reference value of the signal-noise ratio of the signal with which a positioning mark is detected by an electron beam is calculated from the signal obtained by scanning an electron beam 5 on the optimum pattern located on a wafer 1, and the selecting range of the signal-noise ratio of the signal of a positioning mark detecting signal is established. When an exposing process is going to be performed on the signals obtained by scanning an electron beam on the mark 3 of a chip 2, the signals having too small or too large signal-noise ratio which is beyond the range of selection are excluded, and the mark position is distinguished using the signals within the range of selection. For example, a large peak appears when a substance having different atomic weight is adhered to the surface of the wafer, and a little peak is generated by the recesses and protrusions on the wafer surface, but the erroneous recognition of the above as a positioning mark can be prevented remarkably by properly selecting the signal.

Title: Memory area control system for collection of garbage
Inventor: HASHIMOTO YUKIKO
IPC: G06F12/00
Filed: 1989-02-28
Abstract: PURPOSE:To shorten the processing time for collection of garbages by releasing an old space of a real memory after the end of a copying process and supplying an instruction to a virtual memory not to page out the releasing contents of the old space to an auxiliary memory. CONSTITUTION:When a processor 1 is started, a list process means 10 uses one of two areas, e.g., a memory area 20 of a real memory 2 of a virtual memory mechanism 5 as an old space to perform a list process. Then a new cell is added and the area 20 is used up. Thus an unused cell recovery means 11 is started to use the other area, e.g., a memory area 25 of the memory 2 is used as a new space. At the same time, the working cells 21-1 to 21-4 of the area 20 are gathered and used as cells 26-1 to 26-4. Thus a real memory release request means 12 is started. The means 12 produces an instruction to release the area 20 out of the memory 2, and a virtual memory control means 3 releases the area 20 from the memory 2 and sends an end report to the means 12. The means 12 outputs an instruction to the means 3 not to apply a page-out process to the contents of the memory area 20.

Abstract: PURPOSE: To perform drawing easily with one unit of press without causing creasing and cracking in a molded article by tentatively molding a flat plate material to a fixed shape by means of a punch, pressing the edge part thereof and lowering the punch in this state.  
     CONSTITUTION: A flat plate material W is placed on the die face of a female die 16, and an outer slide 17 is lowered down to the bottom dead point so that the gap of a length A is maintained between a blank holder 18 and the material W. An inner slide 22 is then moved downward to lower a punch 23 and force the material W in the hollow curved surface direction of the female die 16. The head part 24a of a damper means 24 is pressed by the flange part 23A. However, the head part 24a hardly displaces and urethane rubber 20 displaces. The holder 18 also lowers by the length A. At this time, the bead 21 of the holder 18 begins to penetrate in the circumferential edge of the material W, and the material W is drawn.

Abstract: PURPOSE:To obtain an ultrasonic motor in which a rotating state is not affected by a state before a driving frequency is converged by providing inhibit means for inhibiting an operation of follow-up means when reaching an optimum driving frequency, and release means for releasing an inhibit if a deviation signal is output. CONSTITUTION:When a CPU 15 of a driving circuit writes data corresponding to an initial driving frequency in a counter 12 at the time of starting to drive an ultrasonic motor 14, an oscillator 11 starts to oscillate. Then, whether an output signal S0 of a D-flip-flop 30 is an H level or not is checked, and data of the counter 12 is so altered and output as to lower the driving frequency if it is the H level or to raise the frequency if it is an L level. Then, if it is recognized that it once reaches an optimum driving frequency and is then varied from a low frequency side to a high frequency side, a tracking is stopped, a mode for checking output signals of D-flip-flops 31, 32 is started. If an output signal S1 is an H level or an output signal S2 is an L level, the driving frequency exceeds an allowable value, and hence tracking of the optimum driving frequency is restarted.

IPC: H01C17/06
Filed: 1989-03-01
Abstract: PURPOSE:To lessen variation of the resistance value under service by covering the surface of a thin resistance film, which is formed on an insulated base board with certain patterns, with a protection layer of glass type followed by fusion welding, and then baking the thin resistance film. CONSTITUTION:The surface of a thin resistance film 2 formed on an insulated base board 1 with certain patterns is covered with a protection layer 3 of glass type and fusion welded to the film 2, which is then baked. Thus the resistance element is prevented from oxidation due to atmosphere used by means of fusion welding of the protection layer 3 to the resistance film 2, and change in the resistance value under service is suppressed, and baking of the resistance film 2 can promote its recrystallization before the use as a heater. This can suppress change in the resistance value under service.
